While Test Drive Unlimited blurs the line between single-player and multiplayer racing better than anything that's ever tried it before, it's not quite a slam dunk. But even with its limitations, Test Drive Unlimited's concept is executed well enough to make it an addictive and interesting racing experience. Unlike the other home versions of Unlimited that have been released recently, the PSP version can't be immediately dismissed if you've played the 360 version, since it's different enough to not quite be the same game all over again, and being able to race around Hawaii against your online buddies while you're on the go (as long as you're near a Wi-Fi hotspot, of course) is really something else. Again, you can't call it the very best version of the game out there, but this is one case where PSP owners most definitely did not get the short end of the console-port stick.

Test Drive Unlimited was originally built around the idea of removing the distinction between single and multiplayer racing. Unfortunately, most of what made that idea so fresh and unique doesn’t hold up well on the PSP. On the plus side, the impressive technology and solid racing make this game worth a look anyways. Driving around Oahu on a handheld is pleasant in its look and relaxing in its feel. The idea of a Massively Open Online Racer didn’t quite come through, but the end result on the PSP is a solid racing game even if it doesn’t match up in terms of content or structure with the PC or Xbox 360.

Overall, Test Drive: Unlimited is a good game that gamers who enjoy games from the driving genre. It has a large number of features, for both single- and multi-player modes. While it is not as strong as releases from the Gran Turismo, Test Drive: Unlimited is probably the best driving game out there for portable on-the-go gaming. So, until Gran Turismo for the PSP is released, this game is your best bet for a racing game.
